We've got a variety of swings in our backyard. The grass doesn't seem to grow beneath them. To solve this we placed mats under the swings, for cushioning. To hide the dirt and mud. These mats are durable easy to set up and have made a difference. It was a task to level the ground under the mat, which has been great for preventing dirt and mud build up and making swinging more enjoyable for my kids. I'm really happy, with this product! I ended up ordering more to place under all our swing areas.
